Bread and Butter (BB Cross-chain Liquidity)

Last updated
Bread and Butter is BounceBit Chain's innovative cross-chain liquidity scheme, designed to bridge $BB to major EVM-compatible blockchains and the Bitcoin CeDeFi ecosystem. This strategy builds on BounceBit's CeDeFi infrastructure, combining secure custody, asset management, and DeFi elements to enhance user engagement and ecosystem sustainability.
Just as bread and butter form the foundation of a meal, this liquidity scheme establishes $BB as the core asset ("bread"), with liquidity pools and channels acting as the "butter," spreading utility across multiple networks. The system operates through integrated bridge protocols, maintaining deep liquidity pools on leading EVM networks where $BB can be paired with native tokens and Bitcoin-based CeDeFi assets.
When users initiate transactions on their preferred networks (like Ethereum or BNB Chain), the Bread and Butter scheme automatically manages liquidity flow through integrated bridge protocols. Each transaction contributes to balanced liquidity channels, with arbitrage mechanisms smoothing out price differences across chains - just like butter spreading evenly on bread.
The cross-chain bridge implementation leverages LayerZero's Omnichain Fungible Token (OFT) Standard. This standard provides atomic cross-chain message passing with guaranteed consistency and enables seamless token transfers across supported networks.
BB currently is only available on Ethereum and BounceBit Chain, more chains might follow in the future.

The OFT standard implements unified interfaces for cross-chain token transfers: Documentation:
This interface handles:
Cross-chain token transfers with atomic execution
Message validation and consistency checks
Gas fee management across chains
Refund handling for failed transactions
The intent-based trading system allows users to engage with $BB and other BounceBit ecosystem tokens without needing to switch networks. When users purchase tokens on platforms like Ethereum, liquidity automatically channels back to BounceBit Chain, ensuring efficient cross-chain accessibility.
Note: This documentation is maintained by the BounceBit team and is regularly updated to reflect system improvements and new features.
Initial implementation includes:
First bridged tokens: $NOTBB and $LNNG
Support for major networks: Ethereum and BNB Chain
Direct trading using native tokens (ETH, BNB)
Automated liquidity channeling back to BounceBit Chain
Future ecosystem tokens will be added based on community demand, continuously expanding the reach and utility of the Bread and Butter liquidity scheme.
To bridge tokens, users can access the official Bridge Portal: . The interface provides a straightforward process for cross-chain transfers, automatically handling the complexity of the OFT protocol implementation.
